RFLink with FW that receive from RFLink with out FW

[denisj]

Hi there all,
I just receive 2 kits of the RFLink.

One of this I charge the firmware and I linked it to my domoticz raspberry and it's work great

The other RFLink hardware (arduino + RFLink),
I want to use it in a garden project and I want to make my custom schetch on it, so I don't want to upload all library firmware on it.

So how can I use the hardware of the second RFLink to just send
via 433Mhs a "Hello world" to the first RFLink (domoticz) please ?

I need to upload just a lib in order to send/receive from Domoticz.

Thanks all
Denis

You are sure?
Just a lib?
Then why don't you do that?
And then let us know how you did this, I'm very curious

[denisj]

I'm sure that just a lib can be suficent in order to make work the rf part.
But that's not the real problem... can be 2 or 3 or 4.

What I want is to use the second arduino+RFLink
for other projects and put my sketch inside.

Thanks
Denis

I'm sure ....

Always good to read, no help nessecary then
Good luck

and put my sketch inside.

What sketch ?

[denisj]

I will write a sketch in order to mantain my future hydroponic garfen.
And from the garden I will send statistics about PH, nutrient, water level etc... to domoticz.

Before to begin I want just to send a Hello World msg. to
domoticz server.

Thanks again
Denis

Now that I'm home I can show you a better sample:

Code: Select all

#include <VirtualWire.h>

const int led_pin = 11;
const int transmit_pin = 12;
const int receive_pin = 2;
const int transmit_en_pin = 3;

void setup()
{
  // Initialise the IO and ISR
  vw_set_tx_pin(transmit_pin);
  vw_set_rx_pin(receive_pin);
  vw_set_ptt_pin(transmit_en_pin);
  vw_set_ptt_inverted(true); // Required for DR3100
  vw_setup(2000);	 // Bits per sec
}

byte count = 1;

void loop()
{
  char msg[7] = {'h','e','l','l','o',' ','#'};

  msg[6] = count;
  digitalWrite(led_pin, HIGH); // Flash a light to show transmitting
  vw_send((uint8_t *)msg, 7);
  vw_wait_tx(); // Wait until the whole message is gone
  digitalWrite(led_pin, LOW);
  delay(1000);
  count = count + 1;
}

Did you see ? ...there it's just an include cmd... the "VirtualWire.h" one, so just one lib.
This lib use another RF hardware.
So what I want is to use something like this with the RFLink hardware,
for this reason I buy 2 arduino+RFLink hardware.

So is there is something also for the RFLink hardware ? in order to use it with out the complete firmware.

And yes... I'm sure can be done, but I don't know how with the Aurel Tranceiver... for this reason I ask on this thread.
If you don't understand what I want, just ask and I'll explain better.
If you understand what I want but you don't want to help, please don't make a bad jokes.

Thanks again
Denis
